My current team's Alakazam, Infernape, Palkia, Carnivine, Skarmory, and Rhyperior. Palkia's a bit of an OP crutch, and i'm leveling up a Kingdra to replace him (and yes, the rhyperior is terrible rock/ground combo, but it knows rock wrecker, megahorn AND ice-beam).

yyyyyou don't need it? you can still beat the elite 4, and then you get to go to some crappy island, where they give you a 2x2 square to walk around in. there's lots of doors everywhere, but people won't let you through unless you've got your national dex.

well it's not a one-size-fits-all pokemon. i personally only use it when i know i've got something super effective to slaughter with it (Blissy and Breloom would totally go down from my Alakazam, btw). Going against a Heatran or a Dragonite would be absolute suicide though. that's what ice and water attacks are for.

Alakazam is a very fast pokemon with extremely high sp. attack. it can learn focus blast, which is a super powerful fighting attack that goes off of the sp. attack stat. fighting is super effective vs. normal. even with 255 HP, it's a losing match.

With blissey, i ain't expecting any one-hit-KOs, for sure. but it's got an attack of TEN, and it's special attack is fairly low too. Personally, i'd most likely be using my infernape vs. a blissey, but Alakazam could hold his own.
